Cement work typically costs $8-$18 per square foot for a basic poured concrete surface, while small jobs may carry a $500-$1,500 minimum charge. Total price depends on project size, concrete thickness, finish, site access, removal needs, and local labor rates; cement is the binder, while most slabs and driveways are made with concrete.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic concrete slab | $8/sq ft | $12/sq ft | $18/sq ft | Usually includes placement and a standard finish |
| Concrete walkway | $8/sq ft | $12/sq ft | $16/sq ft | Small projects may have a minimum charge |
| Concrete driveway | $8/sq ft | $13/sq ft | $18/sq ft | Reinforcement or demolition can raise the price |
| Stamped concrete | $12/sq ft | $18/sq ft | $25/sq ft | Decorative patterns and color add labor |
What a Standard Concrete Slab Costs by Square Foot
A straightforward 400-square-foot patio or utility slab generally runs $3,200-$7,200, with about $4,800 typical for a basic finish and ordinary access. A small pad under roughly 200 square feet may cost more per square foot because setup, delivery, and crew time are spread across less area. The estimate assumes a prepared, reasonably level site and a 4-inch slab; excavation, reinforcement, and premium finishes may be additional.
For a standard residential pour, budgeting $10-$15 per square foot is a useful starting point. Regional labor and site conditions can move a quote outside that range. Assumptions: typical U.S. suburban labor, standard ready-mix concrete, normal access, and no major demolition.
Concrete, labor, and prep line items in a quote
A written estimate should identify what is included rather than show only one square-foot price. The following ranges reflect common residential work; they can overlap when contractors bundle site preparation and forming.
| Quote item | Typical price | Common unit | What changes it |
|---|---|---|---|
| Ready-mix concrete | $125-$180 | Per cubic yard | Mix strength, delivery distance, and order size |
| Placement and finishing labor | $3-$8 | Per sq ft | Finish type, crew access, and pour complexity |
| Base preparation and forms | $1-$4 | Per sq ft | Grading, gravel depth, and form layout |
| Reinforcement | $0.50-$2.50 | Per sq ft | Wire mesh, rebar size, and spacing |
| Removal and disposal | $2-$6 | Per sq ft | Existing concrete thickness and hauling access |
Labor, preparation, and demolition can rival the concrete material charge. For labor estimates, a crew of three or four may spend 8-12 hours on a typical one-day residential pour, with additional time for excavation or complex forms.
How slab thickness and access change the estimate
Thickness has a direct effect on concrete volume: a 4-inch slab uses about 0.0123 cubic yard per square foot, while a 6-inch slab uses about 0.0185 cubic yard. A 6-inch driveway or equipment pad therefore needs roughly 50% more concrete than a 4-inch surface of equal area, before accounting for waste. Rebar, heavier mix specifications, and thicker compacted base also add cost.
Limited truck access can add $500-$2,000 or more if the crew needs a concrete pump, extra labor, or repeated wheelbarrow trips. Slopes, soft ground, drainage work, and tight property lines may require grading or retaining work beyond the basic pour. Assumptions: concrete volume calculated before waste; pumping and site work are separate where needed.
When does stamped or colored concrete raise the price?
Decorative finishes usually add $4-$10 per square foot over a basic broom or trowel finish. Integral color, surface staining, stamping, and multiple pattern borders each add material or skilled finishing time. A 300-square-foot stamped patio might total $4,500-$7,500 before demolition or major grading, compared with roughly $2,400-$5,400 for a basic finish at the same size.
Ask whether the quote includes color, sealer, borders, and control joints. Those details affect appearance and maintenance, and excluding them can make competing bids look cheaper than they are. Sealing often costs about $1-$3 per square foot when priced as a separate service.
Three project sizes show how totals can differ
A 120-square-foot walkway with a 4-inch slab and straightforward access may cost $1,200-$2,000, or about $10-$17 per square foot, partly because a small-job minimum applies. A 400-square-foot basic patio may run $4,000-$6,000 at $10-$15 per square foot, with a crew working most of a day. A 600-square-foot driveway with reinforcement and removal may reach $7,800-$13,800, or $13-$23 per square foot, depending on demolition and access.
These examples compare different scopes, not fixed national rates. Each assumes ordinary regional conditions and excludes unusual drainage, retaining walls, and major utility conflicts. Assumptions: residential projects, standard concrete, and no premium decorative finish unless specified.
Regional labor rates and concrete delivery affect totals
Prices in high-cost metro areas and parts of the Northeast or West Coast may run 10%-25% above a comparable project in a lower-cost Midwest or Southern market. Rural projects can have lower labor rates but higher delivery charges if the batch plant is far away. Ready-mix suppliers may charge short-load fees for small orders, commonly around $50-$200, and waiting-time fees if unloading takes too long.
Compare local bids using the same dimensions, thickness, mix, and finish. A quote that includes concrete delivery, reinforcement, and cleanup is not directly comparable with a labor-only price. Ask contractors to list short-load, pump, and disposal charges separately.
Repairing cracks can cost less than replacing a slab
Minor crack filling or surface patching may cost $300-$1,000, while larger resurfacing work commonly runs $3-$10 per square foot. These fixes can improve appearance or slow water entry but will not correct a settling base, poor drainage, or widespread structural damage. Full removal and replacement often makes more sense when sections are heaving, extensively cracked, or no longer drain properly.
Get the cause of the damage identified before paying for a cosmetic repair. Replacing a small section may cost $500-$2,000, depending on access and matching requirements, while replacing an entire driveway can cost several thousand dollars. Ask whether repair work includes preparation and a compatible finish.
How to lower a concrete contractor’s quote
Keep the footprint and finish simple, confirm the required thickness with the contractor, and avoid adding decorative borders or color that do not serve a practical purpose. Completing nearby flatwork in one scheduled project may reduce repeated setup or delivery charges. Clearing access and moving obstacles before the crew arrives can also limit extra labor, provided excavation or base preparation remains professionally specified.
Get at least three itemized quotes based on identical plans. Check whether each includes demolition, base gravel, reinforcement, control joints, delivery, and cleanup. Do not cut required thickness or reinforcement just to lower the bid; instead, ask whether a smaller project area, basic finish, or targeted repair would meet the need safely.
